Crypto price checker and freebitco.in auto-roller v1.1
Cryptocurrency Price checker: BTC, ETH and LTC price-pair data are fetched from Bitfinex v2 public API. The real time price and the 24 hr daily changes are provided.
Auto-roller: To use, set the toggle switch to ON and leave freebitco.in open (and logged in) in one of your tabs. The extension does the rolling for you every hour. The popup displays the amount earned, the number of rolls it did in the current session (since the last time it is left ON), an approximate time until the next roll, and the btc balance in your freebitco.in page.
To reset all the statistics saved in the extension, you can simply triple-click the large BTC icon on the top of the popup page.
Some useful links are provided at the bottom hyperlink bar. This is my first practice Firefox add-on, so please let me know if something doesn't work as expected, thanks!
